“Pet” (**1/2 out of four) a tense psychological thriller about a strange and neurotic young guy (Dominic Monaghan) who bumps into an old flame from high school (Ksenia Solo) and gradually becomes obsessed and begins stalking her and then holds her hostage in a cage in his animal shelter but her response to this is far different than what he (and the audience) expects. Extremely well-acted story takes some unexpected twists and is unusually intelligent for this genre but story becomes overly cerebral and unpleasant, especially after she is taken hostage. If the animal shelter set looks at all familiar, it should because it was the same set used for “Saw” which this in many ways resembles.
